[SR-Users] "append_rpid_hf()" and "append_hf()" issues

[Alex Balashov]

Ricardo,

The 'rpid' value is loaded from the 'subscriber' table as part of the 
authentication functions;  if you consume_credentials() before it, it 
will be gone.  You should append_rpid_hf() the RPID header first, and 
consume_credentials() afterward.

Cheers,

-- Alex
